Since the update I haven't been able to make anywhere near as much profit each night around -$10 to $180 instead of $750 a night. I also don't have the option to use Mina in the club even though I have gone through it. Also does the update mean you don't look in on lessons again?

If you have empty slots in your club, it will drastically decrease your income - make sure you can fill all the slots. You might have to fiddle around with the upgrades to not have empty slots remaining.
I said in my devlog that I...forgot to implement Mina in the club :'D I only realized once I had published the update. I will add her in the next update though!
And yeah, you won't look in on the lessons as before. I will try to make up for it in the future, but baby steps.
